Debian bookworm became the new stable in June 2023, so we should update
our containers to use it.

On macOS the update did not cause any issue, and just updating the
suite name worked.
On Windows, it caused some problems where we used the strip provided by
the OS (only for tor, it seems), because the new version of strip seems
to update the timestamps by default.

We are delaying the process for Android because there are still a
couple of projects that require Java 11, which is not available on
bookworm.

We need to do some path manipulation in some Firefox code that is run
before initializing XPCOM.
So, the alternatives are either Path* functions from shlwapi, or
std::filesystem, which is disabled in Firefox 115.

Mozilla enabled it starting from 116, but we have been told it is okay
to enable it also in 115, so we do it with this patch.
